GMMG Question

**Kill98** · 04-22-2006, 06:54 PM

I have a 98 LS1 TA and was wondering about how much HP is netted on average by one of their catbacks.

I have no problem spending the money if this catback is what I want. I'm only thinking about the magnaflow really other than this one, my friend has an LT1 with hookers that sounds good and some clips of the LM sound good but I like the idea of the GMMG the best.

Which catback out of them typically turns the most HP, and which is the loudest?

I've searched and found nothing... Please help!

BTW I'm a Marine so please be civil since I serve you

Thank you!
And I think we would have been mostly civil either way.

Personally I like the Magnaflow catback. Flows as well as the others. The part I like is it isn't too loud down loud but when WOT it screams!!

Most cat-backs are 10-15 RWHP gains.
Flowmaster is the bottom of the barrel when it comes to flow. Just an FYI.
