I've got an 87 mr2 that I'd like to redo the exhaust

>>17356613
4 to 1 for max power

>>17356657
mr2 doesnt have enough space for that my dude

EGR

im so confused

>>17356620
Might be cool but I'd need to find someone who could design some quality headers that would fit. I have to keep 4-2 otherwise

>>17356613
I'm pretty experienced with exhaust setups so I'll answer your question since everyone else is just going to post memes. Setup B is perfectly fine, but whether or not it sounds like shit will almost entirely depend on what mufflers you use (I'm assuming stock header in all cases?). X pipe will be the loudest and will drone, H pipe is generally more tame sounding. Setup C is commonly seen as a factor setup on 4 cylinder cars when the manufacturer wants the car to have dual exhaust tips but wants to keep cost down notice it has about the same amount of piping as setup A and also only uses 1 muffler. It will be the cheapest way to get the dual exhaust look but not the best for performance.

4-2-1 vs 4-1 depends what kind of power you want, 4-1 give the most top end power but 4-2-1 gives more mid range power.

>>17356775
Thanks for the reply. Yeah I'll more than likely be using the same headers unless I can find someone who's worth the time to design all new ones which is unlikely. The current muffler I have is a magnaflow which sounds nice for what it is, so with that in mind I'll probably go magnaflow mufflers for the new setup as well. Cost isn't a concern so I'm not looking to cut corners, you're saying a B setup would be better for performance than C?

>>17356780
A 4-1 would be preferable all things considered since I track the car often. It's a weekend/track car and not my daily driver, and it being a 20v 4age it only makes power at the top end anyway.

>>17356794
Yes B is better for performance because your not merging the pipes like in C which causes more back pressure. Assuming the car is tuned for the setup you don't want back pressure, some people will tell you otherwise but under WOT the less back pressure = the more power. Ideally straight header always gives the most power that's why dragsters don't have exhausts but that's obviously too loud for street cars.

>>17356821
Alright, sounds like I should go with B then.

>>17359580
Why

>>17359594
The sound is somehow incredible.
