I went to a muffler shop over the weekend to get a stainless tip put on my exhaust. To make a long story short I ended up getting a flowmaster 80 series installed with a stainless tip all for $250. Its not to loud on the inside but when you get on it it sounds good and I was very surprised with the performance.

I always get a chuckle when people "can feel" the performance after a muffle swap or some other add-on swap. Their ass must be a lot more sensitive than mine.

Are you saying exhaust systems dont improve performance ? I am not saying it was tons with only a muffler but to me it did feel a little differnt. I also have a Saleen Mustang and did a compltete exhaust system on that and gained 26 HP on the dyno. So maybe your ass is not sensitve :gungrin:

I have never seen a muffler gain more that about 5 - 8 hp, you really can not feel under 10 hp gains, your a$$ must be good. ;)

I'm not saying they don't improve performance. I'm just saying they don't improve it to a "feelable" amount. It's all relative, of course, to the starting HP numbers. Obviously a 25hp gain will be much more noticeable on a 150hp 4 cylinder than it will on a 600hp big block chevy. A new muffler just isn't going to add a "feelable" performance. The new sound can have a way of tricking the mind... it sounds tougher thus feels faster. But it's not. It's like when young kids get new sneakers, they want to show their mom how fast they can now run, but they're not any faster, they just have new shoes.

I also get a chuckle at HP math. My brother-in-law fell into this trap with his mustang until I explained it to him. If you add something that reportedly gives you "up to 20hp" and something else that gives you "up to 10 hp" and another add-on that give you "up to 30 hp". You do NOT gain 60hp. Sorry, it's just not happening that way. One time during testing they managed a 20hp gain on that first part, that's all they needed to make the claim. And, if you put each part on one at a time, tested, actually got those numbers, and took the part off before testing the next part, when you put all the parts on at the same time, you might get 30 or 40 hp (if you were able to get their advertised numbers).

Ok... I'll step off the soap box now.

Anyone try the bassani exhaust system? I would like to get two dual tips coming straight out the back, either I mess with the corsa and bend it so that I get to exits or I buy a new kit, anyone have advice?
