You're adding back pressure so I would assume you may notice a few whp up top more than anywhere else. This may however boost the mid-range somewhat.

Ok yea I figured if lose a lil but if it's not much too notice then it'll b fine with me. Later down the road I'll go bigger exhaust, the exhaust shop I went to only had 2.25" exhaust piping( biggest he had).

Thanks for help man

So why would you buy a little exhaust?

Were you that excited about throwing on a header that you settled for a small exhaust?

Theres piping kits on the internet for cheap that fit correctly.

Ill bet any amount that since this exhaust shop doesnt carry 2.5 and up means they most likely doesnt have a mandrel bender.

With that being said, your 2.25" piping is probably under 2" when you add in the crush bends.

Now you have to replace that when you couldve done it right the 1st time.
This is called throwing good money after bad.

Thia thread should help you save your wallet from buying the same **** twice.

My motor was turboed with just a downpipe with no exhaust system at all, it's how I got the car cause it's meant to drag, so I wanted to do an n/a setup and didn't like the loud open headers, and this shop was closest to me that I could get to without getting pulled over for loud as hell open headers, so I had to settle for 2.25in for now but I will get a better exhaust piping later. It's my dd to work so I had to settle for it. Yea I didn't like to settle for something shitty man, but it's either get a ticket or use cheap piping for now.

No worries though I WILL get a better piping.

Yea that's a great link, took me a while to read it though ( hard to read ) lol. Yea I see what u was saying about the bend from the shop, it has a crush bend and it goes smaller not like bend I see on the website u posted. Really good prices than what I paid for that piece of **** I got on.

Thanks man I appreciate the help

Depends on how much power you are planning to make. I've put 240 whp through a 60mm chambered exhaust. So depending on power, it prob won't hurt u much.

This is true but getting a crush bend exhaust from a muffler shop is the worse. I know because I just went from a crush bend to mandrel bend exhaust and it's like having a street tune done to ur car. It's a day and night difference. Nothing huge but u will notice where the extra hundred went to on mandrel bend pipping
