I ran a new exhaust off the back of my Quad 4 into a resonator muffler out to the tips, the whole exhaust is about 5' long. I love the increase in the high RPM range but it is still a bit noisy.

Are there tips that have anything in them to help quiet things down just a little bit more?

Resonator tips. Pace Setter, Hedman or Hooker http://www.summitracing.com...ty/Dual/?keyword=tip

I used Hooker resonator tips PN 21430HKR on my Indy exhaust.
Still loud when you "put your foot in it", but quiet when cruising, even on the highway.

That wont sound to odd in conjunction with a resonator type muffler?

Try these guys. Reasonable price and they work

I'll get you a picture of what's going back on the quad 4 I'm working on. I just got it running yesterday. It's a new longblock from an 89 Grand Am.

put on a cat and you'll have no exhaust music, easy solution ( imo ). I had cats installed on my 6.6 trans am when the exhaust system was redone ( magnaflow ) and it quieted her down ALOT...i'll post a sound clip.

Well, the CATs undoubtably helped, but, that is not a subtle exhaust. In fact it is pretty loud. The cc inserts will quiet that down quite a bit.

This is what I'm getting ready to install on the Quad 4 I'm fixing for a customer.



I don't know who makes it, it came with the car.

RobsFiero's,

Regarding your pictures, that is exactly what I am doing. I took a better look at the tips that are on my car and they are/were resonator tips, everything is rusted in there and everything is loose.I reached in with some pliers and the inserts came out in pieces.

I would add a cat but there is simply not any room to add it.

I am thinking I will look for a new tip and see if that helps.

Monza also makes a good resonator tip, both in single and dual/split design.
