Will this set-up gain power?

e92335tt · 03-15-2009, 04:09 PM

I would like to do some sort of exhaust set-up with spending the least amount of money. How much power should I expect to gain with this set-up?

Catless DP's with catless midpipes with stock exhuast

Keep in mind I also have a tune and intake

Thanks

Also would the car smell really bad? How much louder will the exhaust get? Does anyone have this done or have any videos of it?

DP's and mufflers seem to be the most restrictive parts to the exhaust.

e92335tt · 03-15-2009, 04:22 PM

Yea but mufflers are too much money and I don't want the car to be too loud

just get Catless Dps than.

It would barley gain power if I just did catless DP's. I would need catless midpipes also to get rid of all of the cats. Im just wondering if I will gain a lot of power with no cats and stock exhaust.

Get catback too. Did you see the ghetto bends in the stock exhaust? I have catback and carted dps cuz I hate the smell.

I have RR Dps and RR midpipes and the difference between my friends AA catback and DPs was only 2whp lol. You will see VERY similar gains with this set up comapred to full catback dont worry.
