Flowmaster 40 Installation

[streetg1202]

got the muffler in the mail today.. dats the good news.. bad news.. took it to a muffler shop and they're tellin me that there is no room.. it sticks out a lil.. i was wondering if any of yall have under the car pix showing how u installed Flowmaster 40 (or just describe what you did).. and did any of you put a heat shield? is it necessary? im hoping to go again tomorrow so fast response would be appreciated

well if you check on here before you go you will get this.....i have the 40 and it can be done........i dont have any pictures but i watched him do the whole thing.....the muffler was shortened almost at each end.......they added an extra brace for support ( i didnt want it wobbling around)........trust me it fits, dont let them tell you otherwise....what kinda tip do u have?? and i didnt put a heatshield on it, theres enough room all the way around it, i dont think it needs it.......let me know how it goes......

I can take a pic tommarrow, but yeah the pipe coming out of both ends of mine was cut off, fits great, try another shop, if they are a descent shop they can do it.

hows she sounding?...

any 3.4's have these? yours a dual or single out?

[streetg1202]

its working/sounding great for me.. deep.. i was short on funding so couldn't afford better ones.. but this is good enouf for me (for now).. mine is single out.. just wish i could find some CAI for 2.2

yeah Alerosport, I'm running a 40 series on mine! I love it!

[bigd6983]

im runnin the 40.......
likes - rumble at idle is decent, not too loud. when you let off the gas in a certain gear 1,2,3 the backpressure sound sounds awesome and mean
dislikes - I want it to sound a little throatier such as slp or the 80 series

[jabartram]

I think mine sounds better than the slp or the 80, I've been asked a few times if my cars runnin an 8cyl.

[bigd6983]

what else r u runnin jabartram.....maybe a set of headers might give it a throatier sound.......and did you go with bigger piping and a higher flowing cat......

do you guys have single or dual out? and... duno if you guys know which part numbers id need for my 3.4.... pics? Whats ur tips look like?

ya I have the 80 series dual out installed w/ DTM 3.5" tips and a magnaflow highflow 2.5" cat on a 3.4L (with the ends kicked up sorry dont have pics right now) and hell yeah the FLOWMASTER mufflers sound amazing! My friend works for GM dealer (14yrs mechanic) when i pulled up to his house he was in his backyard, the first thing he said to me was "wow man that sounds like a small block Chevy" :D . also get looks from ppl at stop lights and other stock alero owners :thumbsup:
