If you don't want to spend too much, check out Megan's site. As "monkey" said, they're cheap, but they sell some stainless ones which look really nice. I've seen one that was used for a while and still looked real good. Had that nice blue to gold apppearence. I don't know about the gains, but you get what you pay for.

 

ya ive heard some pretty good things about megan...the quality is amazing for the price ur paying....i think ima get me one off ebay for like 150 total

 

Hottshot 4 to 1, made for the h22a in a civic.......... increased ground clearence.
I have a JDM header from 94 h22a that i am about to take off my car once my vibrant 4-2-1 two piece arrives.............Let me know if your interested could probably have it to you in a month............. Would have gotten Hottshot myself but couldnt wait for it.......... Have event on the 30th

 

The hottshot dont fit in a lude tho

 

Vibrants tubes are stacked like on a angle also for ground clearence

 

haha no it isn't dude 3.5mm or .14in is a very minimal difference in exhaust sizing.

 

im all ears....

 

Any ideas on pricing for Hottshot or vibrant? I want something better than my DC sports but also need more ground clearance...

 

i got my vibrant header for 425............. its a two piece stainly still, not to sure of the exacts but i am pretty sure it has a larger collecter. Hotshot will run you about the same and is suppose to put down sum crazy power but i have never seen a dyno.

 

Min = Mout from fluid dynamics, so a 3.5mm difference in radius would mean that a 12% difference in sectional area between the 60mm pipe and 63.5 mm pipe.

how that effects flow and the velocity of the fluid is pretty complicated, but it's not a small effect.
