Yeah any off road pipe with SLP is gonna be LOUDDDDDD. You want my opinion? Get a MAC prochamber mid pipe. It sounds perfect with SLP exhaust. rbstang is right though. Even shorties will give you a gain. The headers and heads are the most restrictive part of a stock 2v mustang

 

Thanks guys i really appreciate it! I am pretty sure im gonna go with the BBK shorties now I mean for 159.99 i cant really beat it and this car is gonna be a long process so im just startin off for right now. I cant wait to hear how loud she is with these catless shorties! Ill be sure to post some vids of her when i get it done. Thanks again

 

not really man. i picked up a whopping 9RWHP 9RWTQ when i put my LTs on. i alread had a built motor with stage 3 heads & cams and runing 16 pounds of boost. i think headers in general are a waste in terms of price vs performance.

 

I hate how people say shorty headers are wastes of money. It's amazing the way people think. It's the "go big or go home" mentality. People should learn a little bit before they bash shorty headers.

 

long tubes do get lot more then shorties...

but anyway I would run an x pipe with LM1's... its sick

 

my friend has a o/r x with lm1s and it is SOOO loud, i think u should have gone with LM2s but anyway i like how the X sounds better then the H. and for the shortys, dont get them! i made the same mistake. figured they were a lil cheaper so why not, then realized they didnt do a damn thing and they dont even change the sound really. get longtubes.

 

No, not a lot. I made 6 rwhp with shorty headers. The install was 1/8th the hassle of LTs. Like nanaki said he only made 9/9 on a highly modded motor. The stock manifolds are highly restricted. Whether you go with shorty headers or long tube you'll be happy. Shorty headers don't give you as much as long tubes I understand. But for the cost difference, installation differance, starter replacement issues, ground clearance issues, and not to mention the dropping trans to do clutches, throwout bearings, and/or rear main seals will be so much harder because you're going to have to take off the passenger side manifold. Long tubes aren't worth it on a street car. Do you even know the differance between exhaust manifolds and headers? It's all in the runners. If you get shorty headers that take all 4 runners and dump them into 1 collector you'll make decent power, same as long tubes. I can't justify the PITA install, cost, scraping everywhere, and having to remove one of the headers to get to the trans. Shorty headers FTW!

 

highly restrictive? you made 6 horsepower, i think a frickin throttle body spacer will give you 3.

 

Not to the wheels.

 

Ok last question for you guys. What brands should i be lookin at for these long tubes. I really appreciate the feedback Keep it comin! Hope every one had a great turkey day!
