haha.. fixed lol

i couldn't remember if the GMPP was 2.25" or 2.5"

but yeah i think a catted 2.5" would do justice

 

i think if your not gonna be doing a tvs or turbo swap.. 2.5 will do just fine all the way through.

 

ZZP recommends 1 3/4 primaries for supercharged applications, i was just going
off of that.. You still think they would be too large??

and Nah i dont plan on a blower or turbo swap.

 

clear image suggested the 3"dp with the 1.75... thats what i was basing it from..

it could be becasue i was planning on going 3" cat-back in the future... I would get the 1.75" primaries no matter what.

 

Alright man, cool

i appreciate all the feedback from everyone

but i'm stiil worried about sound lol

 

haha.. if your keeping your cat the sound will be better...

take your car to a local muffler shop, i paid 65 dollars for A resonator AND the welding of it... that takes out ALOT of raspyness..

 

yeah i am getting a catted downpipe.. is that what you mean?

i'm sorry. i'm a rookie to all this performance stuff. i came from the 4X4 game

 

haha.. yes cat = catalytic converter...

resonator is kinda straight through muffler in a sense, but not the same as a muffler...

it burns off excess gases and such like a cat, but using a much different method, is not quite a cat either.....

 

eh i run 3--->2.25 and it is not dangerous as far as my EGT guage reads. The biggest bottlenecks with flow are the cat+dp and the muffler on a stock system. Keep in mind you will lose low end opening it up too much. Many people i know go back to STOCK because they lost so much torque and low end power.

btw im almost 300 hp with the stock blower.

 

i know what a cat is and does lmao.. i'm not that new hahaha
but thank ya for the effort lol

hmm.. but what does it sound like?? clips or vids??

lol

 

one of the best sounding i know of.

ill pm u the clip if u want.

 

sounds good.. a bit like mine does now lol.. maybe a lil louder. Good job.

 

I'll get some fly by vidz but yea. It doesn't sound like a honda over 3000 rpms

 

Quick Q phantom......how do exhaust companies such as magnaflow show a gain from just a 2.5" cat back system and more of a torque gain than hp?
