Mufflers

What is the stock inlet size of the mufflers?

Any suggestions on which mufflers sound the best (and not "ricey") and add the most horsepower

1 7/8" inlet 2.25" outlet. Try Flowmasters they sound good and aren't that expensive for what you get.

Re: Mufflers

I don't personally have any experience with them, but (ironically) I've heard flowmasters aren't that great for flow. Check out Magnaflow or vortex...

Re: Mufflers

I was thinking about going with the Dynomax Super turbos. They sound good and they are inexpensive

What is the stock exhaust pipe size before the y?

I have the 40 series Flowmasters and I think they sound great for a V6. I paid $120.00 for 2 of them on ebay with free shipping. Everyone who has heard it, likes it. A couple people said it sounds like a V8. I think it sounds like a V8 only at idle though. I also had a hi-flow magnaflow cat put on at the same time. It feels a little bit more peppy then it did. Hope this answers something.

Re: Mufflers

I agree that the flowmasters sound great at an idel, but they seem to make a whine at higher RPMs. I've heard the dynomax's and they seem to keep the deep sound better at higher RPMs. Plus I can get 2 Super Turbos for the price of one 40 series.

Does anyone know the exhaust pipe diameter before the Y?

2.25 inches from the cat to the Y.

Re: Mufflers

I have a pair of SLP stainless steel mufflers off my 2000 GTX. (GTP) They are good as new. $50 for the pair. It's a steal!

How long have you been trying to sell the mufflers. You are aware we have a Car Parts for Sale forum you can use. See link below:
