lol i had alot of suporters lol notice how i was wanted back and every one clapped when tc dude was gone lol

 

tCDude needs a shrink with his multiple personality syndrome.

Kittens on the other hand...

 

Well a 3" is justifiable at the 400whp+ mark IMHO. Until then, you're just tooting your own horn. You will meet plenty of other exhaust restrictions before you meet that exhaust restriction. We have made over 400whp on the 2.5" setup, FYI

 

I like to toot...

 

In my opinion going to the larger exhaust may not net a significant gain... The diameter of the pipe will contribute hp output but not as much as the length of the pipe...

With larger pipes come larger heat loss... The trick is to keep the exhaust temp high so it keeps moving... As the gas cools it slows down and creates back pressure (something you obviously are looking to eliminate)... Best bang for your buck is an exhaust cut out... It will reduce any kind of back pressure at the point of the cut out and a 3ft long 2.5" dp to a cutout will match if not out flow a full 3" exhaust...

Further more with a cut out, you can have the exhaust loud or quiet, depending on you mood...

Its really person perference, but a full 3" exhaust does look mean if you have the extra cash to do it.

 

Yeah! Someone else studied thermal dynamics and flow.

I've been preaching this same mess for the past 3 years on here and still no one wants to listen

 

We the few must lay down the laws of logic so the demands of many can be met with purpose... J/K

 

 

I like to think im putting my 3 inch exhaust to good work even though im not at that number yet as my car has 0 hp right now but bu the time i get the motor back in i will be using it all the way hoping it dosent atract to much attenti

 

it will draw attention when you get on it

 

it draw attention asap its loud i mean really really loud

 

lol at your sig scott, you will get tomas confused haha..

anyway i was thinking of upgrading my 2.5" dp/spipe/spipe back to full 3" but i guess im just gonna stay at 2.5 for now and save the money for something else.. but i have a huge dent on my downpipe so i prolly have a 2" section in my dp haha, will do the tune and dyno first and see if i can get to my goals

 

dont ban kittens lol and you have a huge dent how did you manage that?

 

haha i didnt do anything to the dent yet lol, its prolly a deep 5 inches long dent haha.. i'll see if that thing will hurt it power much
