Slp Loudmouth Exhaust

I just picked this up but didn't recieve it yet. Is it a 3 inch?

How much of a difference are this and my air foil going to make?

I currently only have a K&N Cold Air kit installed.

GMHTP got 30whp with the K&N, Air Foil and Magnaflow 3".

Thanks,

Dan

Yeah, mine was 3". I wouldn't be expecting 30 rwhp by any means...call me a pessimist, but I just don't see it as happening.

LM is 3" then after the y after the axle it goes to 2.5". you can expect 20 horse from stock with a CAI and catback such as the LM.

Air foil is like 2 horse Iv heard, I dout you will get 30 horse, but put on a set of headers with that slp and your power will surely make it to and past 30 horse. 30 from stock that is.

Gmhtp got 30 from intake, airfoil and exhaust. I was just hoping for the same. Their car is identical to mine except mine is black.

If you want some advice, toss the airfoil.

Here's my car with a Loudmouth. Of course, it has a few other "things," also.

first of all, dont pay any attention what anyone says unless they are a regular joe who is in the same boat and he actually has experienced it. especially magazines and parts stores. theyre all in business to make money.

throw on the LM, a set of LTs with an ORY pipe and it will start making some ponies. however you might not like the sound. its extremely racey sounding, loud and obnoxious when you get into it at the right moment. i can tell you right now it wont sound deep, low or muscle sounding, but then again, people dont look at my car cause its quiet.lol
