Mufflers
So I'm thinking about getting the flowmaster super 10s - the flowmaster super 40 delta flows are louder, but id like it to sound meaner. I was wondering if there would be any difference of running a one single in/dual out muffler with two pipes running out the back and running two actual mufflers?

Re: Mufflers
I don't know the answer to your question. I do know that the GXP's sound good but don't have much power. Personally I'd slap some mufflers on there and call it a day.

Re: Mufflers
Has anybody used spintech pro street 9000's that's what I'm putting on next month. Ive had the 10 series flowmasters on several v8s and they sound like a 40 series compared to the spintechs. Maybe these will help with the raspy sound these engines have.

Re: Mufflers
For your 3800, almost any muffler will sound relatively the same. The 3800 is an awful sounding engine, I'd say to leave it alone. I have Flowmaster 44s on my car and I like it. Slightly deeper and louder than stock.

Re: Mufflers
How does the bonneville gxp mufflers sound on the SSEI anyone ever try them?
Re: Mufflers
Also are the pipes the same diameter?

Re: Mufflers
I think Pat has them on his 2003 SSEi, and they're whisper quiet.

Re: Mufflers
correct, they are maybe slightly louder than stock, but they do have a larger diameter muffler inletnos4blood70 wrote:I think Pat has them on his 2003 SSEi, and they're whisper quiet.
