Summit Racing Muffler

[PReta]

i just put one of the summit racing mufflers on my eta. and its has way too much interior drone, but perfect sound on the outside. i've never had a aftermarket muffler, but its pretty cool to be able to set car alarms off at the local mall parking lot.
its got single offset 2.25 inlet and center 2.25 outlet.
part number is SUM-638221


what would be the best way to get rid of the annoying interior noise?

Resonator

does size matter when it comes to resonators?

[Asbradley21]

Get one that's about 18in. from your local muffler shop, probably won't cost but about 20 bucks installed. That's what I did when I removed my cat. You can see it almost touching the ground in my sig.

but i need my cat because of california law. and is your resonator a glasspack? i heard that those wear out pretty quickly.

[Asbradley21]

You don't have to take out your cat. And my car is really loud without it. Leave it, put on a resonator. It might be a glasspack, didn't take any note, but it's been on there a while with no problems.

is the stock resonator the little part thats after the flange? can i cut that out and put a resonator there?

[Asbradley21]

Yep and yep.

i just put on a 18 in magnaflow resonator right after the cat. and it definitely made it more quiet. the drone is cut down. but is it normal to smell something burning?

i want to say no, but it could just be becuase its new. do you smell it in the car with windows up?
