Currently my mods include s/c, bosch 110, greddy sp2, kn filter and hc screen removal. I'm contemplating the megan spipe and midpipe but was wondering if anyone had opinions/facts on whether this would be a good choice for a performance increase. I know a higher flowing exhaust is a must for a turbocharged vehicle, but does the addition of a supercharger also warrant a higher flowing exhaust? Possibly an s-pipe only with the stock cat and midpipe? Let me know your thoughts, thanks.

 

Gains with higher flowing exhaust will be less significant for the SC than for a TC application.

 

I definitely plan on going full exhaust in the future. I can't help but feel like the stock exhaust is too restricted.

 

I would say it helps quite a bit. I have a MMW Header, and had a HKS axleback when I was dyno'd with a NST Pulley and CAI, got 230whp. Stock Mid still though, so still room for a little improvement im sure.

 

I would love to get the MMW header spipe combo but I would need in writing from the dealer that they would not void the warranty because of it. Also I'm not sure how annoying the buzzing in higher rpms would be.

 

Legally they can't. If something does go wrong with the car, the only way they can legally void your waranty is if they can prove that a specific part caused the failure, "Header." Magnuson Moss Act, look it up.

 

When you get the s/c it doesnt say anything about voiding your waranty due to installing a header. It does however say that they will void the waranty if you change/tamper with the s/c... that they can do.

 

Yeah I've read the trd warranty. I think I will give them a call and see what they say about the header tomorrow. I was dead set on the 9.5 psi pulley but I've convinced myself not to do it. If something goes wrong I will be kicking myself.

 

i read an old old thread about the stock header being better than an aftermarket on the S/C........i guess it was all bs huh?

 

Not sure but I think I am going to just add an spipe and custum mid pipe and call it a day. I don't want to remove any cats. I love the way my exhaust sounds now and I would hate the rasp from a header.

 

but if you do a custom mid pipe (just add a high flow cat & large resonator) you will have little to no rasp

 

i was thinking about a TSUDO midpipe and a CC spipe, would that work out good with a trd axleback and a S/C ?

 

i dont think it would be a problem since the only drawback to the TRD axleback is just adding a header, assuming you don't have one

 

yea dont got one. just wondering if the gains would be even worth it.

 

probably not, s-pipe back would get i dunno 5-7 whp?

 

gotcha. that sux.

 

yeah you know i plan on getting the S/C real soon as i was just gonna have my greddy sp2 exhaust on it only. i currently have the injen cai and aw header w/ megan s-pipe but i think im gonna sell it because i rather be safe then to have an extra 10-15 whp. and im a DD anyway so i wanna keep it extra reliable, i just want the S/C for that extra push

 

The greddy sp2 is definitley the best sounding in my opinion.
