what if i just put a flowmaster exhaust on my car will that make a difference in performance and sound or just sound?

 

Flowmaster does not make an exhaust for the TL so in essence you are just putting on mufflers unless you have a custom exhaust made including the pipes all the way up to the 3rd cat. Just mufflers = no power just sound. If you change the piping as well to larger you may gain a few hp... You probably would be better off just doing like a stage 3 exhaust mod if you want sound, cheaper and easier...

 

Stage 3 exhaust ? 3rd cat I'm not following ? Um I'm still new to all this modifing stuff you follow? Lol.

 

You sound like I did a month ago.

A Stage 3 Exhaust removes the resonator & 3rd catalytic converter.

 

Actually a stage 3 exhaust mod removes resonator and midmuffler and adds a Dynomax "resonator". Let me find the link...

 

You're right.

 

Sam, it depends what you are looking for if it is sound this is the way to go. I have stage 3 ande love it!
Compilation of all stages of exhaust resonator modification.

So Aznbo took the time and made this post so all of the new people don't have to go through 20 pages of discussion.

So far, there are 4 stages of this exhaust mod.

Stage 1.
Least noticeable in exhaust note increase.
Configuration:
Stock exhaust.
Remove mid-muffler. Replace with 2.5" straight pipe. Everything else remains stock.
Cost: Can be anywhere from $30-$60 w/aluminized pipping.

Stage 2.
A tad louder than stage one, a bit more pronounced tone.
Configuration:
Stock exhaust.
Remove mid-muffler. Replace with 2.5" straight pipe.
Remove stock resonator. Replace with Magnaflow resonator part# 10416.
Magnaflow resonator is a 14" long resonator, which dampens and changes the note of the stock exhaust a bit more, thus you get a bit more loudness/tone.
Cost: Magnaflow resonator costs around $60. Install ranges from $60 -$90 w/ aluminized pipping.

Stage 3.
(Tone result TBA)
Stock exhaust.
Remove mid-muffler. Replace with 2.5" straight pipe.
Remove stock resonator. Replace with Dynomax resonator part# WLK-24215.
Dynomax resonator is a 12" long resonator, which is a bit shorter and less dampening than the magnaflow resonator, thus it should give you a bit more loudness/tone than stage 2.
Cost: Dynomax resonator costs around $40. Install ranges from $60 - $90 w/aluminized pipping.

Stage 4.
Loudest setup out of all 3. Has a bit of a rasp, similar to M3 exhaust setup.
Stock exhaust.
Remove Mid-muffler. Replace with a 2.5" straight pipe.
Remove stock resonator. Replace with a 2.5" straight pipe.
Cost: Can be anywhere from $40 - $60.

Note: If you live in a climate that is prone to rain, snow, rust, Stainless steel pipping is highly recommended.
This also does not prevent you from passing smog, as it does not alter the characteristics of the catalytic converters, but it does not mean that this is street legal either as it does alter the stock setup of the exhaust.

 

Thanks man !!! I think ill go with the stage one and see how that works I want it to be a little louder but not so much that ill have a headache plus I want to have peace in the car I don't want it to sound like my old truck that I would have my music full blast and I could still hear the exhaust
