will switching my stock mufflers with flowmaster 40s sound better?

I've always been a huge fan of flowmasters....i was looking to get teh flow masters axleback for my 06 gt and i love the sound clip on - on AM...but reading some of the reviews they say its just 2 flow master 40 mufflers + tips for 400$.

so if i just replaced my stock mufflers with flowmaster 40s and kept my stock tips would it sound nice?

Flowmasters sound great. I worked with a guy that had Flowmasters on his 2012 gt. cs. I have gt 500 on mine (2012 gt also) He complimented the sound on mine and said he loved the sound. I also thought his sounded great too. Flowmasters were a little louder. Not much. GT 500s were cheaper. As for tips they come already on the axel backs so no reason to change them. Also the bigger diameter on Flowmasters looks way better (4 inch tips) vs. (stock is 3 inch)

Yes, they will sound better but not buy a lot. Same tone but a little louder. If you want it a lot louder you may want to look at other options. I went to a single chamber race muffler because dual chambers weren't gettin it done for me. When I get on it, people are hurting their necks turning to look. Haha.

I was looking at just getting the mufflers from an autoparts store and keeping the stock tips (it would cost 180$ compared to 400$ for the axleback kit which is the same mufflers with the 4" tips) - would that make it not sound as good? - you make a good point though, them 4"tips could give me some +aesthetics.

They sound perfect to me on the sound clips - or is it because they have the 4" tips? if i just replace the mufflers and keep the stock tips will they not sound good?




thanks heavy metal!

And that's all that matters. As far as the tips, it would be logical that if you went down to a 2" tip it would change the sound. So you would think going to a 4" would add something to it. I still have my stock 3 inch. Someone who's done that swap should be along soon then we'll both know. Haha.

The tips on these cars are so short they do nothing to change the sound. If you like the sound of the 40's, get em and have a muffler shop weld them in place of the factory mufflers.

If it were me I would not mess with that. I would do the bolt in. Unless you do the welding it will cost more to transfer tips and you would need brackets welded to the right location. Its not extremely hard but just sounds like more work then needed. GT 500 mufflers, pype bombs, are cheap flowmasters slightly more. Also if you don't like the sound you will have butchered your stock piping. Just my 2cents.

I had Flowmaster 40's welded to stock axleback piping and reused the stock tips. I liked how it looked stock but louder. Let me find a video and I'll upload it.

does all that really cost LESS than buying the complete axle-back kit and bolting it up yourself?

Sorry I thought I had a video but I changed them out for Mac's 2 years ago and all my videos from then are on my old phone.

It was cheaper. $60-70 each for the mufflers, $60 each to weld them up - tips, hangers, and all. Fit was perfect since the axleback pipes were never removed and the mufflers were held up on a stand then welded in place. Better fitting that way than any cat back or axle back I've installed on any vehicle. Only con would be the unpainted aluminized mufflers started to rust in the typical areas Flowmasters rust.
