MSP Apex Cat-back

[YayArea420]

I have the TH SMIC, TH Hard pipes, an Apex 2.5 DP w/cat, soon an Injen intake and I am thinking about getting the Apex cat-back. Is there any increase of HP over the stock cat-back, also if any one has this how loud is it and do you have any sound clips?

 

[biochembruin]

don't know about the hp gain, but this might help with the sound clips. there may be a set-up similar: http://www.msprotege.com/forum/showthread.php?t=43030&highlight=mega+exhaust

A catback is good for a few WHP. The car will be somewhat loud without resonators and one cat.

Does it have a high pitch ricey sound or a nice deep sound? Also I was thinking of getting the black muffler, I haven't seen one in person but it might look good on a titainium with the hyper siver rims.

Also if you buy it from apex that is the N1 muffler on it right?

The sound is very deep actually. Inside you'll probably get droning in mid range rpm

Did you get the Kartboy exhaust hangers when you got this or is the exhaust fine without them?

 

[CustomMSP]

well actually I don't have the Apexi catback, but I have a replica made by me. And no I don't have the kartboy hangers. The stock hangers are fine.

I went with the apex DP and the thermal R&D because I didn't want to have a hella loud exhaust,and it is with the apex cat back,plus there is a wait of a couple weeks to get one,because they are made to order,and it takes a while to get them back from the jethot guys.

Does the thermal R&D perform better than the stock cat-back?

Yes!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Any aftermarket catback will perform better than the stock one.
Bigger piping, better bends, less restrictive muffler and resonator (if applicable).

Where is it the cheapest at? Corksport sells them but they are pretty expensive there.

FROM apex $550

Apex catback also goes under the rear axle so if you're lowered chances are you'll scrape around.

I still have the stock suspension, but thanks for the heads up!
