Cutout ?s

[JoeliusZ28]

What exhaust do you have again, Joel? Obviously not Flowmaster since you said it was the best flowing and we all know Flowmaster is barely better than stock...

I had an SLP 2OTL

Mike, my car loses tq too down low but it ran equally better up top. Definitely faster with it open.

SO what muffler do you guys run if FlowMaster is so bad?

[JoeliusZ28]

their catback is poor but i wouldnt say everything of theirs is bad.

im buying a pair of flows for mine real soon.

Last time I saw a flow test Flowmaster was the worst flowing catback system on the market - and just BARELY flowed better than stock.

That said, Magnaflow, Borla, GMMG all flowed great (of course)

I only have a muffler (FlowMaster 80) on my car and that has a 3" system with no cat and LT's.

I just love the sound but if I can get 10-20 more I'll change.

i like flowmaster ... i would like a link that shows the difference in the catbacks & not just word of mouth

I have heard that its the dual chamber Flowmasters that suck. Single chamber mufflers like the super 40 flow very good I believe.

[JoeliusZ28]

find a link on that?

cause im planning on getting 2 chamber flows really soon. But with dual 3" i dont think il have a problem regardless. 1 chambers are too loud.

B put these in a sticky & lock it its very good info .. if you have anymore post it

[Phantom409]

That is some good info B, Thanks

I have a 3" inlet to a 2.5 outlet on my FLowMaster.

Ya, Lick it and stick it!!!!

moved to a new thread in the Intake/Exhaust and stickied.

There is a guy on this site that dynoed open and closed and gained 20rwhp. I can't remember how modded he is though, I will see if I can find a post where he talks about it.

I have an intake, mild cam, long tubes, 4" y-pipe, and the stock catback. I wouldn't expect 20 rwhp on a stock car with the cutout open or even a modded car with an aftermarket cat-back.

Lol, I remembered that you said that, but I had no idea that your car was as modded as it is.

I have a flowmaster cat-back with a 4inch cut out that I leave open it sounds good and is not super loud

I have the magnaflow too and love it

I have the magnaflow too and love it, they are cheaper on ebay but I wanted a warranty (the salt on the roads here in winter kills an exhaust) so I got it here magnaflow 16908, or you can try one of the vendors here, they are always running sales/specials. either way its a great system and very easy to install.
