Let everyone list there exhaust set ups, and what they think about them. sound? power gains? look? also, opinions on best full exhausts and/or mix and match set ups. ex: RB header,Bonez high flow cat, corksport 3" catback.



Let the thread beging!







Also....Price for set ups and where to find these would be helpful to all us rotor heads. https://www.nopistons.com/forums/pub...1047683473.gif

I made my own. RB header with my homemade collector, three inch to the magnaflow, small resonator, and three in to the axle. ITs loud, its annouying, but it works.

our race car has a similar header/collector with an rb turbo back pre silencer and a magnaflow fart can. all with 3" pipe. its quiet and works pretty well

I have the Racing Beat true dual header, presliencer, and y-pipe and then bought some ebay mufflers for like a 100 bucks for both. The pipe between the y-pipe i had done at a local shop so its not that great of quality but i had ran out of funds for good stuff. The sound is not too bad except when you hit about 3,100 rpms the tone is just at the right pitch to be annoying but otherwise i love it. Power gains im not sure becuase i don't really remember what it was like before i added it. I could be wrong but i think the price ended up being around 800 or so.

Damn man I spent less than 100 bucks on mine

NoeVuh 11-01-2005 12:05 AM

haha yes but RB has done research in their product and i do not have the best access to things to do a lot of my own stuff.

fc3s4utnv 11-01-2005 12:44 AM

True, when I get mine on the dyno soon I will let you guys know how it does.

Yeah, im interested. What do you expect out of it, any ideas?

RB Header, eliminated the main cat with a test pipe, and a Borla Cat-Back system. Around $800 for everything.

test pipe? what do you mean? and what kinda power gain did you see?

sublimike 11-01-2005 01:35 PM

Stock header, corksport 3" downpipe, jc whitney high-flow cat (it's tiny), and 2.5" borla split/dual exhaust w/ "intercooled" mufflers. i like it a lot, sounds pretty badass, not super loud or annoying, definite power gain and i've seen a drastic improvement in gas mileage!

sen2two 11-01-2005 01:36 PM

I wanna use the Racing Beat (true dual)Road Race header with the Road Race presilencer. i dont wanna use the rest of the racing beat exhaust and don't want two mufflers. what exhausts' will fit to the RB persilencer that are single exhaust?



Also, what other "presilencers" will fit to the (true dual) RB header?

for some reason 3000-3200rpm is loud on these cars. and its right at a normal freeway cruise rpm too

I know, it can get quite annoying, especially when listening to music or talking to someone on the highway.

This is for NA application?



The hot setup I think personally is SDJ header. Then you need to get a shop to make you up a connecting pipe to the racing beat's turbo back presilencer, Y pipe and cans".



All your tuned flow is taken care of by the SDJ header, and after that you have to try to silence the flow. So the RB turbo back's presilencer and cans. They are designed for the heat too.

Looking on racingbeat's site, what's the purpose of a megaphone for exhaust?

I didn't know racing beat used a megaphone. But in fluid dynamics, when you incraese the diameter of the pipe, from x to X+1" or whatever the flow through it will slow down. By slowing the flow you are dissipating energy which is sound energy.

Then you can apply flow in = flow out

where does this mega phone thing go? where the presilencer would go? if so, there would be much less restricion than a cat or presilencer. does it quiet it down much?

thats for the imsa cars, that setup is 2x42mm pipes, they collect somewhere around the rear axle (230mm long), and then theres that collector and megaphone tip. its super duper loud, like you can hear it across the paddock DURING a race loud.



might be a good way to go from one size pipe to another though

thats not how sound works, its irrelevant in fluid dynamics. The (mega) (phone) is called that for a reason. https://www.nopistons.com/forums/pub...#>/BURNOUT.gif

Im hoping for 150's at the highest, but Im expecting 130's to 140's.
