Help: Off Road H-Pipe & Saleen Magnaflows = Too Raspy

[WvPower]

I Recently put on a off road h-pipe to go along with the stock saleen magnaflow exhaust. I am hot happy with this setup as it is too raspy for my taste. I would like to know if there is any kind of reasonator i could get or diffrent muffer I could use to help with rasp. My car is a 06 sc281 saleen. I wont want to change much as my car is tuned along with going on the dyno so I dont want to affect the tune.

Hmm, same issue with my off road x pipe...couldn't stand it anymore and ended up installing high flow cats on the x pipe.

I have a Off Road Mac Prochamber on my car and its somewhat raspy... The tone is similar to an Off Road H Pipe but its not as loud. I think the off road H pipe would sound good and I was actaully thinking about taking my mac prochamber off of my 07 and putting an off road H pipe on. What brand is your H pipe? Would you like to sell it? PM me, I may be interested. I havent heard another one with an off road H pipe but I think it would sound good. Thanks.

Niceeeee. Thanks I think that sounds really good

I tried the the off road H-pipe and hated the way it sounded. I put on a catted x pipe and its pretty quiet until you get into it.

I was just about to install my o/r h pipe today but now I think I'll wait and order some hiflow cats and weld then on. What do you guys think maybe if he kept the h pipe and installed resonators? Would that help or just be a waste of $

Here is mine with Kooks Lt's and catted X pipe.

Hey guys thanks for your input. Dont think its looking too good for me unless I put cats back on then. Im so dont want to just the fact Im afraid of throwing off my tune. Would then putting cats back on affect my tune that much ?

Hey thanks also. Hopeed I helped ya then also. Yea I was thinking also if by installing reasonators would help me out and would they affect my tune.

[tungmetal06]

Resonators would probably not affect your tune. Cats on the other hand might because of back pressure and what not. Check with your tuner.

Stock Saleen exhaust and a catted JBA x-pipe sounds the best!!!

[XxBoostinxX]

I always enjoyed the sound of the mac prochamber. It is nice and deep and not nearly as high pitched as some X's or H's. Here is a sound clip of a member on the forum:

Would love to hear it with some LT's though

Thought I would just post here instead of start a new thread... I just installed a pypes h pipe with stock magnaflows and it too is ridiculously raspy when I get on it. If I baby it through the rpm range it stays low and deep. If I swapped to flowmasters will this help? I know an h pipe with flows on my fox body sounded awesome and I would loke to come close to that. It seems to me its just the magnaflows that are the culprit but thought I would seek all your opinions here! ! Thanks!!

Cats or no cats?

Hey Jason, No Cats... I really don't want to have them... It really seems like the muffler may be the cause of most of the trumpeting.. I realize putting the cats back on will knock some of that down..

[mattman215]

I've got kooks headers, kooks catted intermediate pipe with the saleen center exit axle back setup and it's definitely got some noise to it when you step on it. The car also has cams so that will have an impact on its sound, the photo below is a video of the car with a bit of throttle.

Good luck come smog time. Which Magnaflow's did you go with? SS series is a traditional looking muffler can, and a Magnapack looks like a polished tube?

[Faceseat831]

I had the factory saleen "regular looking magnaflows" but just swapped them out for 40 series flowmasters.. sounds AMAZING!! it has a tiny bit of rasp but I actually like it. The magnaflows sounded terrible when I got on it but the flows sound great. Almost like my old fox body. Couldn't be happier it is really loud with the pypes h pipe. Cost me $150 as it was trcky to keep the center exit took some manipulating to get the flowmaster in because they are longer. Anyway I highly recommend pypes h pipe and 40 series flows. Anyone who says flows dont sound good on these cars is nuts!!

Can you post a video so we can hear it?

[Faceseat831]

Yea ill try to get one up this weekend. It is definitely loud! Im sure a set of high flow cats would sound nice too with a little less trumpet but I like the way it sounds

It sounds like the internal baffles in the Magnaflows may have been broken. It happens over time. Keep an eye out for rust on the new mufflers. Enjoy!

[Faceseat831]

You are probably right jason I was thinking the same thing! Yea unfortunately the flows do rust :(

Go to Home Depot. Grab some Rustoleam black BBQ paint and paint the mufflers and attaching points. This will help, especially where you live. That paint has ceramic in it and will help prevent the rusting quite a bit.

[Faceseat831]

Will it smell like bbq when they get hot?? :)

Maybe if you throw a few steaks on them!

[msb7144]

Need to hear it!!!! I have high flow cats and a JBA H pipe and have long wanted to do the Flowmasters but wanted to hear them first. What part number Flows did you get exactly? Did you install them yourself? I know these exhausts are tricky with the limited space and center outlets.

[07S281SC111]

msb7144, Do you have a sound clip of your car? I just put magnaflow High-flow cats on my car with the stock h-pipe and it seems pretty raspy. I thought it would only add a bit of ummphhh to the exhaust but it created a seemingly totally different beast. Just want to see if yours sounds the same. Thanks in advance.

[msb7144]

I don't but I can make one. My problem will be trying to figure out how to post it here, lol.

[Faceseat831]

Alright guys so here goes.. im kind of backing off my original post. At first I thought the catless h pipe and flows sounded great until I drove it on the freeway and for a few days. It still trumpets a lot on the freeway or anytime n heavy load conditions. Car was waaayyy too loud I got tailed twice through parking lots by local PD which ive never had any attention from them at all. All in all I was not happy. Too loud. Still trumpeted and popped bad on decel. I ended up putting the stock h pipe back on and left the flowmasters on. Car sounds REALLY good now. Definitely not as loud but has great tone. I still wish it was slightly louder but the flows are a lot deeper and healthier sounding than the magnaflows. I didn't get around to making a clip before it drove me nuts but here is a link to a video that sounds exactly like my setup with O/R h pipe and flows.. I rec cats though. The trumpeting went away with cats back on. I hope this helps you guys. Im curious about high flow cats now... maybe ill get a little more loudness without the trumpet? Most peeps seem against them... heres the clip... https://youtu.be/4iYjrVSVRIQ

The 3v don't sound good without cats. I've tried multiple combos and its always too loud, too raspy, too much drone without cats.

[msb7144]

I want to hear it on a Saleen. Maybe its me but a GT with Flowmasters sounds a little different than a Saleen, I don't know if its because of how the exhaust is run or the if the center plus the down turn tips all make a difference.

I just removed my high flow cats "hollowed them out" since they were coming apart anyway and I think it sounds much better. I am running shorty headers, stock H, and stock Saleen exhaust. 1 thing of note is that I keep the Saleen "dumps" closed at all times. No drone, no rasp.

[msb7144]

Wont closing the dumps restrict exhaust flow? The pipes going from the muffler to the center outlets are small with some tight bends.

Probably, but not enough to make much of a difference in my case. I am running 16 psi and about 700 rwhp and I don't see a difference in boost open or closed. Also, if I go racing, I can just push a button and open them up.

How did you close the dumps? Cap them? Weld plates? I have reason to believe that a lot of the bad exhaust notes may be coming from this side of the exhaust.

I have a 2005 with the vacuum actuated butterflies. I put a control module on the vacuum line to those valves that allows me to turn then on or off with the press of a button.

Ah! I'm trying to figure a way to cap them, but not permanently in case it really doesn't make a difference. Any ideas?

Thanks! Lots of work, but I am VERY happy with the outcome. It's still technically for sale, but I have been back and forth whether I should take it off the market or not. It's just such a well rounded car and it would take a lot of money to get anything else to come close to this car's performance.
